CHEESE-PRESS.

SPECIFICATION forming part of Letters Patent No. 572,455, dated December1, 1896.

Application filed August 13, 1895. Serial No. 559,112. (No model.)

To all whom it may concern:

Be it known that I, LOUIS SIGM'UND, of Na perville, in the county of DuPage, and in the State of Illinois, have invented certain new and usefulImprovements in Cheese-Presses; and I do hereby declare that thefollowing is a full, clear, and exact description thereof,referencebeing had to the accompanying drawings, in which- Figure 1 is a view inside elevation of my cheese-press; Fig. 2, a vertical section on line wx of Fig. 1, and Fig. 3 a horizontal section on line 3 y of Fig. 2.

Letters of like name and kind refer to like parts in each of thefigures.

The object of my invention is to provide a machine for making cheesewhich will be thoroughly practical and will turn out a superior grade ofcheese; and to such ends said invention consists in the cheese-presshaving the construction and combination of parts substantially ashereinafter specified.

In the carrying of my invention into practice I support from a suitableframe A, composed of wooden bars or beams bolted together, afunnel-shaped hopper B, arranged with its axis in a Vertical line andwith its naled within suitable bearings provided upon the frame and towhich is secured a bevelgear G, that meshes with a like gear H upon ahorizontal driving-shaft I. Within the hopper B the shaft F is provided.with a spirallyarranged series of radial arms or blades f f, that havetheir faces arranged at an incline, so that as they cut up ordisintegrate the curd they will feed the same downward through thehopper. The portion of the shaft within the extension 0 is tapered downto a point,

and upon it is a screw conveyer f, that engages and forces the materialdownward.

Surrounding the cylinder D is a jacket K, between which and the cylinderis left a space for steam to heat the latter, steam being admitted nearthe upper end of. the cylinder through pipes L and L, entering thejacket upon diametrically opposite sides, and discharged therefrom nearthe lower end through pipes M and M, also entering the jacket atopposite points. The upper end of the jacket is threaded to engage acoupling N, that is flanged to overlap a flange c at the bottom of thehopper extension 0, between which flange and the upper end of saidjacket a flange upon the upper edge of the cylinder is clamped and thusall three parts held together by the single coupling N.

The interior of the cylinder is coated or lined with pure block-tin, andthe screw is similarly coated, which material, after much experiment, Ihave found will not cause such discoloration of the cheese as occurswhere other metals are used. For a like reason the hopper proper is madeof sheet-tin or other sheet metal lined with tin, and the hopperextension 0, which is preferably of cast brass or bronze, is also linedwith tin.

The operation of my press is as follows: The shaft F being rapidlyrevolved, the curd is placed in the hopper, and, moving downwardtherethrough by gravity and the feeding action of the arms f and f, isout very fine by the latter. Upon reaching the screw f the latter forcesthe finely-subdivided curd through the hopper extension Cand into andthrough the cylinder, the tapered portions of both of which, by offeringresistance to the passage of the curd, cause the same to be closelypacked or compressed into a coherent solid block by the time it emergesfrom the cylinder. During the passage of the curd through the cylindersteam is circulated through the jacket surrounding the same for thepurpose of lubrication, and as such steam is admitted and dischargedupon the two'sides of the cylinder a perfectly uniform temperature allaround the latter can be maintained, so as to result in the desiredamount of heat being applied to the entire surface of the curd in thecylinder. Lack of uniformity in the heat results in the scorching of thecheese if the heat be too great, or if it be too little in the adhesionof the cheese to the cylinder and its consequent crumbling or breaking.One or the other of these results is bound to occur if, for instance,steam is admitted only at one side of the cylinder.

After a batch of curd has been run through the press it is desirable toclean the latter, and for this reason the connection between the hopperand cylinder is one that permits of their ready and easy separation.

Having thus described my invention, What I claim is 1. Ina cheese-press,the combination of a hopper having a flanged extension, a cylinderhaving a flange abutting against the flange of said extension, a jacketencircling the cylinder, with its end engaging the cylinderflange, and aflanged coupling engaging the jacket and the hopper-flange,substantially as and for the purpose shown.

2. In a cheese-press, the combination of a hopper having a flangedextension, a cylinder, having a portion of its interior tapered, andprovided with a flange abutting against the flange of said extension, ajacketencircling the cylinder, steam-pipes com municatin g With thespace between the jacket and cylinder, at opposite points, and a flangedcoupling, e11- gaging the jacket and the hopper-flange, substantially asand for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this8th day of July, 1895. v

LOUIS SIGMUND.
